Guided learning

Learn the forces

Ten narrated lessons, each inside a live laboratory. Every lesson works differently — an experiment, a puzzle, a guided flight, an investigation, a decision — and every answer comes from the physics.

1. Interactive experiment
Weight: the force you always carry
Change gravity and payload; watch the weight vector and the thrust it takes to hover.
8 min · 4 steps
2. Component exploration
Making thrust: Newton’s third law
Take a propeller apart in your head: blade angle, RPM, airflow, reaction.
10 min · 4 steps
3. Guided flight
The balance of hover
Fly the F450 to a hover and read the free-body diagram while you do.
8 min · 3 steps
4. Physics puzzle
Why multirotors tilt to move
A rotor only pushes along its axis — so to go sideways, the whole aircraft leans.
10 min · 3 steps
5. Comparative demonstration
Turning without pushing: yaw
Two rotors spinning opposite ways cancel each other’s torque — until one speeds up.
8 min · 3 steps
6. Engineering investigation
Drag, wind and top speed
Investigate how drag grows with speed — and what it takes to stand still in wind.
12 min · 3 steps
7. Scenario decision
Thin air
Hot, high and heavy: decide whether a flight is a good idea.
10 min · 3 steps
8. Comparative demonstration
Wings versus rotors
A wing needs airspeed; a rotor makes its own. Find the stall.
10 min · 3 steps
9. Failure analysis
Ground effect and the vortex ring state
Two ways a rotor’s own downwash changes its thrust — one helps, one hurts.
12 min · 3 steps
10. Mission simulation
Power, batteries and endurance
Why a bigger battery doesn’t always fly longer.
